In this paper, we propose adaptive convergence security policies and management technologies to improve security assurance in the home networking environment. Many security issues may arise in the home networking environment. Examples of such security issues include the user privacy, the service security, the integrated networking security, the middleware security and the device failure. All these security issues, however, should be fulfilled in phase due to many difficulties including deployment cost and technical complexity. For instance, fundamental security requirements such as authentication, access control and prevention of crime and disaster should be addressed first. Then, supplementary security policies and diverse security management technologies should be fulfilled. In this paper, we classify these requirements into three categories, a service authentication, a user authentication and a device authentication, and propose security policies and management technologies for each requirement. Since the home gateway is responsible for interconnection of many home devices and external network access, a variety of context information could be collected from such devices.

A campus network nowadays adapts the security policies in detail and even in variety, along with firewall based access control. Nevertheless, security threats, such as information hacking, intrusion and DoS, are not decreasing yet. This paper proposes an enabling method of discriminative security policies to enforce an adaptive security for security objects on basis of the security elements. The security level of a security devices is decided based on the mapping between the users and the objects. The proposed security policies could improve the security effect in terms of investment in creative campus environment, and aim to provide fast and stable services to users.

The final aim of South Korean policies on North Korea and reunification of Korean peninsula is to reflect the direction and the form which South Korean authority has been pursuing. To achieve this aim, we must establish the forms of reunification and continue to prepare for contingency plans while focusing our effort to those policies. In pursuing peaceful reunification, the national security should not be neglected. Moreover, the policing policy is one of the important national security policies. In order to draw up more effective policing policies in a reunified state, this dissertation establishes some preparing measures on policing conditions and expected problems resultion from the reunification of Korean peninsula after studying similar problems in formerly divided countries. The chapter one shows the direction of reunification policy. The chapter two looks some policing problems in formerly divided countries The chapter three studys the expected policing conditions and preparing measures after the reunification of Korean peninsula The chapter four reposes some reasonal solutions for peaceful reunification.

The purpose of this research is to explore ways to improve private security officers' compliance with security policies by analyzing the effects of transformational leadership and organizational trust. Data were collected from private security officers employed in the cities of Seoul and Busan by using survey questionnaire. Statistical analyses were conducted with SPSS 22.0 and AMOS 23.0. The results showed that transformational leadership increased organizational trust which was found to have a positive effect on willingness to comply with security policies. In addition, transformational leadership did not affect willingness to comply with security policies directly but had an indirect effect on it through organizational trust. The findings of current research suggest the leaders of security businesses consider various ways to increase officers' organizational trust such as improved job security and benefits in order to maximize their willingness to comply with security policies.

This paper addresses the problem of protecting security policies in security mechanisms, such as the detection policy of an Intrusion Detection System. Unauthorized disclosure of such information might reveal the fundamental principles and methods for the protection of the whole network. In order to avoid this risk, we suggest two schemes for protecting security policies in Snort using the symmetric cryptosystem, Triple-DES.

Especially, system security is very important in the ubiquitous environment. This paper proposes a protecting scheme for security policies in Firewall and intrusion detection system (IDS). The one-way hash function and the symmetric cryptosystem are used to make the protected rules for Firewalls and IDSs. The proposed scheme could be applied in diverse kind of defense systems which use rules.

Many studies have been done on secure operating system using secure kernel that has various access control policies for system security. Secure kernel can protect user or system data from unauthorized and/or illegal accesses by applying various access control policies like DAC(Discretionary Access Control), MAC(Mandatory Access Control), RBAC(Role Based Access Control), and so on. But, even if secure operating system is running under various access control policies, network traffic among these secure operating systems can be captured and exposed easily by network monitoring tools like packet sniffer if there is no protection policy for network traffic among secure operating systems. For this reason, protection for data within network traffic is as important as protection for data within local system. In this paper, we propose a secure operating system trusted channel, SOSTC, as a prototype of a simple secure network protocol that can protect network traffic among secure operating systems and can transfer security information of the subject. It is significant that SOSTC can be used to extend a security range of secure operating system to the network environment.

This paper proposes CPR(Computer-based patient record) system that is utilized in Ubiquitous environment, establish security policy by analyzing security limitation of system and design suitable security system in CPR system. The present study designed a CPR system and, for the development of a security system, established security policies for the CPR system through analyzing the operating environment and vulnerability in security and designed a security system implementing the policies. The security system supporting CPR system is composed of authentication system, XML documentation and encryption of medical information and network security system.

As new technologies emerge and threats become increasingly complex and unpredictable, security professionals who are living in the age of information face an increasingly complex array of challenges. In recent, virtually all organizations with physical and IT assets protect those assets in a variety of methods. There are physical systems to protect facilities and their contents from unlawful trespassing. It is important to note that the integration of physical and IT security is to be required: When done correctly, the integration starts with laws, strategies, policies and procedures. Integration of physical and IT security systems is done not for its own sake but in support of security policies and procedures. Significant security improvements can be made by integrating physical and IT security management without necessarily integrating physical and logical electronic security systems. Up to now, the private security industries of the Republic of Korea have been operated and developed by the separation of physical security and industrial security. However, considering the fast changing security environments, physical security companies should turn their attention to security convergence field to cope with the new trends in the security matters. At the same time, governmental supports on the improvement of various laws, regulations and policies in such a way to meet the realistic needs of the industries should be followed.

Since the recent COVID-19 pandemic, Internet usage has increased rapidly and companies have shifted to telecommuting. In addition, as more time at home increases and network traffic through streaming services such as games, the Internet, and Netflix increases, cyberattacks and threats are also increasing. Many countries around the world, including Korea, the US, China, and Japan, have various cloud security policies, but they continue to suffer from various vulnerabilities and cyberattacks. This paper analyzes the current cloud security policies of each country and presents a plan to strengthen the cloud security policies in Korea.
